Larger of two numbers is nine less than four times the smaller number if the sum of two numbers is 76 find both numbers

Respuesta :

x + y = 76

x = 4y - 9


4y - 9 + y = 76

5y = 65

y = 13

Answer:

17 and 59

Step-by-step explanation:

Given: Larger of two numbers is nine less than four times the smaller number. The sum of two numbers is 76.

To find: Both the numbers

Solution:

Let the smaller number be x and the larger number be y.

It is given that the sum of the numbers is 76.

So, [tex]x+y=76[/tex]

Also, the larger number is 9 less than 4 times the smaller number. So, we have [tex]y=4x-9[/tex]

On substituting [tex]y=4x-9[/tex] in [tex]x+y=76[/tex] we get

[tex]x+4x-9=76[/tex]

[tex]5x-9=76[/tex]

[tex]5x=76+9[/tex]

[tex]5x=85[/tex]

[tex]x=\frac{85}{5}[/tex]

[tex]x=17[/tex]

So, the smaller number is 17  

larger number is [tex]4(17)-9=59[/tex]

Hence, the smaller number is 17 and the larger number is 59.
